Is lifted upward by a lower-side lifting unit 8 provided on the lower bottom side of the lower tank 4, and then passed to the upper-side lifting unit 9 via the lower guide pipe 13, the relay portion 14, and the upper guide pipe 15. The game ball A that has been fed in is pushed up by the upper side lifting unit 9 to be sent and stored in the upper tank 5 via the upper delivery pipe 16 and the stored game ball A is stored in the pachinko machine. Circulation of the game ball A that is supplied to 2 is performed.
[0004]
For example, as shown in FIG. 6, the lower-side lifting unit 8 has a plurality of rows, for example, four rows, in a direction perpendicular to the paper surface of the figure by arranging pawls 41 that swing the game balls A by the cam wheel 40. Are arranged in the circumferential direction of the two rotors 21, 32 while being arranged in the same manner, provided with a conveying mechanism for conveying so as to be lifted by the larger rotor 21 and fed into the lower guide tube 13, and the spring 43 A detent mechanism is provided for preventing the game ball A from returning backward by the detent pawl 44 pushed in step (b). The cam wheel 40, the rotor 32, and the rotor 21 are rotated at a predetermined rotational speed by a gear mechanism that is linked to the shaft of the drive motor 23 with a reduction gear.
[0005]
The lower guide tube 13, the upper guide tube 15, and the upper delivery tube 16 are composed of four tubes that guide the game balls A that are transported in four rows, one by one. The lower guide tube 13 and the upper guide tube 14 are relayed, and the return ball of the game ball A is blocked by a detent claw (not shown) similar to the detent claw 44.
[0006]
The upper-side lifting unit 9 is a part constituting a ball feeding and polishing device, and rotates and conveys the game ball A so as to be lifted upward, and sends it to the upper delivery pipe 16. A game paper A is polished by contact with a polishing paper 110 of a polishing paper cassette 100 described later.
[0007]
As shown in FIG. 7, the upper-side lifting unit 9 also has four rotors 52 (52 a, 52 b, 52 c, 52 d) arranged and fixed side by side on the main shaft 51. A gear 53 is fitted to the end of the main shaft 51 protruding outside the unit side plate 50, and the gear 53 is engaged with a pinion gear 55 of the drive motor 54 via a gear 56.
[0008]
U-shaped grooves 62 are arranged in the circumferential direction on the outer peripheral portion of each rotor 52, and the game balls A are taken into the U-shaped grooves 62 and rotated and conveyed. The upper-side lifting unit 9 is configured to lift the game balls A in four rows, and the U-shaped grooves 62 of the adjacent rotors 52 are arranged with a phase shifted by ¼ pitch. Yes. Thereby, the game ball A is not locked simultaneously.
[0009]
Further, a rubber ring 63 made of silicon rubber or the like is provided at the bottom of the U-shaped groove 62 of each rotor 52, so that the game ball A conveyed by the rotor 52 does not rotate inside the U-shaped groove 62. Thus, it is structured to be pressed and fixed. It is also described that instead of the rubber ring 63, a rubber chip or the like may be embedded in the bottom of each U-shaped groove 62.
[0010]
Further, as shown in FIG. 8, a game ball guide 64 having an inverted U-shaped game ball passage 64a is disposed on the left side of the rotor 52 in the periphery of the rotor 52. A game ball guide 65 having an upright game ball passage 65a is provided. Then, the rotation of the rotor 52 of the upper-side lifting unit 9 is slightly faster than the rotation of the rotor 21 of the lower-side lifting unit 8, so that the game ball enters the inverted U-shaped game ball passage 64 a of the game ball guide 64. Does not generate a clogged state. In other words, the game ball A lifted by the lower-side lifting unit 8 is prevented from being pushed into the upper-side lifting unit 9. For this reason, the game ball pushed up in the game ball passage 64a freely falls in the direction of the rotor 52 from the apex.
[0011]
Further, facing the game ball passage 64a, a rubber-made cylindrical lock prevention roller (lock prevention means) 66 is disposed at a position facing the game ball introduction portion of the rotor 52. The roller 66 is fixed to a rotating shaft 67 that is rotatably supported by the two unit side plates 50, and the tip of the rotating shaft 67 protruding outside the side plate 50 has a tip as shown in FIG. A gear 68 is fitted, and the gear 68 is meshed with the pinion gear 55 of the drive motor 54 via the gear 56. The lock prevention roller 66 is rotated in the reverse direction at a circumferential speed that is approximately the same as the circumferential speed of the rotor 52. Thus, when the tip 62a of the U-shaped groove 62 of the rotor 52 presses the game ball A, the game ball A bites into the lock prevention roller 66, and the frictional resistance between the lock prevention roller 66 and the game ball A is reduced. Rapidly increasing, the game ball A is rotated in a direction opposite to that of the anti-lock roller 66 and escapes from the locked state.
[0012]
As shown in FIG. 10, an upper guide tube 15 is connected to a lower portion of the game ball guide 64 by a metal fitting 69, and an abrasive paper feed roller (drive roller) 80 is provided at the center of the game ball guide 64.

The pinion gear 86 is connected to the gear 95 through a gear train of gears 90, 91, 92, 93, 94, and the rotation of the main shaft 51 is decelerated and transmitted to the drive shaft 83 of the abrasive paper feed roller 80. Then, the drive roller 84 is rotated. The drive roller serves as a paper feed drive source for the abrasive paper cassette 100, and the rotational speed of the drive roller 84 controls the paper feed speed.
[0014]
Further, the upper delivery pipe 16 is connected to the upper part of the game ball guide 65 by a metal fitting 70. In the game ball guide 65, as in the case of the lifting unit 9, a guide claw 71 is disposed at a position facing the rotor 52, and a leaf spring 72 is provided in the center portion inside the game ball guide 65. A biased stopper 73 is provided. The stopper 73 is for preventing the rotor 52 from reversing due to the dead weight of the game ball staying in the upper end delivery pipe 16 when the drive motor 54 is stopped.
[0015]
As a result, the game ball that has been taken in and transported into the U-shaped groove 62 of the rotor 52 is guided into the game ball guide 65 by the guide claw 71 and is also prevented from being reversely fed by the stopper 73. It rises as it is pushed sequentially from the lower side. Further, a hook member 77 including a shaft 74, a spring 75, and a lever 76 is disposed below the stopper 73, and supports one end of the polishing paper cassette 100.

Furthermore, unwinding / winding reels 108 and 109 are attached between the frames 101. A polishing paper 110 as an abrasive member is wound around the unwinding reel 108 in a roll shape, and the polishing paper 110 unwound from the unwinding reel 108 is extended in an arc shape along the rotor 52, and the winding reel 109. It is designed to be wound up by The abrasive paper 110 is sent in synchronization with the rotation of the rotor 52. That is, by slowly winding up by the cooperative operation of the take-up reel 109 and the driving roller 84 and the driven roller 107, the upper surface of the cushion 105 runs slowly.
[0018]
A gear (not shown) fitted to the driven roller shaft 107 is a gear 114 (see FIG. 7) attached to the rotary shaft 109a of the take-up reel 109 via a gear train of gears 111, 112, and 113, as shown in FIG. 8), and the winding speed of the winding reel 109 is faster than the peripheral speed of the driven roller 106. As a result, the abrasive paper 110 is in a state in which it is braked by the driven roller 106 when it is wound around the take-up reel 109 and does not become slack.
[0019]
As shown in FIG. 10, two U-shaped grooves 117 are provided on the lower side of the frame 101, and the shafts 108 a and 109 a of the unwind / take-up reels 108 and 109 are provided in the U-shaped groove 117.

When the polishing paper 110 is replaced, that is, when the unwinding / rewinding reels 108 and 109 are replaced, the hook member 119 is slid to the left in the figure, and after the reels 108 and 109 are attached, the hook member 119 is released. Is returned to the right side by the reaction force of the arm 119b, and the shafts 108a and 109a are securely locked and supported.
[0020]
When the abrasive paper cassette 100 is attached to the upper-side lifting unit 9 by the hook member 119, the abrasive paper 110 passes between the driving roller 84 and the driven roller 107 and makes a round on the outer peripheral surface of the backing plate 104 to the take-up reel 109. It will be in the wound state.
[0021]
When the rotor 52 is rotated by the drive motor 54, the game ball A held in the U-shaped groove 62 of the rotor 52 and rotated and conveyed is rotated in the U-shaped groove 62 of the rotor 52 by the rubber ring 63. Thus, when the game ball A is in sliding contact with the polishing paper 110, the game ball A is rubbed and polished by the polishing paper 110 without rolling to the polishing paper 110.
[0022]
Further, at the lowermost end of the unit side plate 50 of the lifting and polishing unit 9, a paper breakage detecting means 120 comprising a light emitting portion and a light receiving portion is disposed so as to notify when the polishing paper 110 is used up.
[0023]

DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to the drawings.
[0028]
In the ball feeding / polishing apparatus of the present invention, as shown in FIG. 1, a rotor 52 attached to a main shaft 51 rotated by a drive motor 54 is fixed to the main shaft 51 by, for example, a key 57 and rotates together with the main shaft 51. A pair of left and right interlocking rotating members 52L, 52R (this member corresponds to a holding bulging portion as defined in the claims) in which U-shaped grooves 62 are arranged in a circumferential direction, and this interlocking rotating member 52L , 52R, and is rotatably mounted on the main shaft 51 by, for example, a bearing or the like, and has a rubber ring 63 on the surface (this member corresponds to a holding bottom portion in the claims). ).
[0029]
Other structures such as the game ball guides 64 and 65 and the polishing paper cassette 100 are disclosed in Japanese Patent Application Nos. 8-76600, 8-309797, and 9-81561. The mechanism is freely applied.
[0030]
Therefore, when the rotor 52 is rotated by the drive motor 54 and the game ball A held in the U-shaped groove 62 is rotated and conveyed to the upper delivery pipe 16 side while being pressed against the polishing paper 110 of the polishing paper cassette 100. In addition, since the rubber ring 63 that forms the bottom of the U-shaped groove 62 is rotatable with respect to the main shaft 51, the game ball A and the abrasive paper 110 are rotated when being conveyed to the upper delivery pipe 16 side. Is larger than the force for rotating the rubber ring 63, the rubber ring 63 rotates while rotating in the U-shaped groove 62 and is transferred to the polishing paper 110. As a result, the game ball A is polished by the polishing paper 110 over a wide portion of the surface thereof.
[0031]
Therefore, for example, as shown in FIG. 4, the upper side lifting unit 9 provided in the lifting passage of the game ball A that connects the lower tank 4 and the upper tank 5 is a pachinko that is configured by the ball feeding and polishing apparatus having the above configuration. On the island 1, the entire surface of the game ball A can be polished even if the number of circulating balls is small, and the tobacco ash and the like adhering to the surface can be removed.
[0032]
In addition, since this invention is not limited to the said embodiment, various deformation | transformation implementation is possible in the range which does not deviate from the meaning as described in a claim.
[0033]
For example, as shown in FIG. 2, a braking means 59 using its own weight or the elastic force of a spring is installed, and the rotatable member 58 is pressed against the main shaft 51 by the stress F to rotate the rotatable member 58. It is possible to adjust the easiness so that the polishing force by the polishing paper 110 and the polishing range can be adjusted.
[0034]
Further, instead of the rubber ring 63, the pressing force when the game ball A is rotated and conveyed by the rotor 52 is not substantially deformed, and is made of a self-lubricating resin such as a nylon polyacetal resin. It is also possible to provide a hard ring 63A between the interlocking rotating members 52L and 52R.
[0035]
In this case, if the surface of the hard ring 63A is formed flat, the game ball A swings in the left and right direction in the direction of the main shaft 51, that is, the gap between the interlocking rotating members 52L and 52R, and twists the polishing paper 110. For this reason, the abrasive paper cassette 100 may not be able to wind up the abrasive paper 110. Therefore, a concave portion 63a having the same curvature as that of the surface of the game ball A, for example, is provided in FIG. It is preferable to provide as shown.
[0036]
By configuring the rotatable member 58 of the rotor 52 as described above, the game ball A can rotate stably when being rotated and conveyed, and the polishing effect of the game ball A by the abrasive paper cassette 100 is thereby improved. Increased further.
[0037]
The U-shaped groove 62, that is, the shape of the outer periphery of the rotor 52 that holds the game ball A and rotates and conveys it, can be the same as that of the actual application No. 9-81561.
[0038]
Further, the polishing member may be a material that can be polished, not an abrasive paper, may be an abrasive cloth, and may be an abrasive leather, regardless of the material.
[0039]
【The invention's effect】
As described above, according to the present invention, since a wide portion is polished by one ball feeding polishing, light dirt such as pachinko balls to which tobacco ash or the like adheres can be completely removed even if polishing is performed less times than before. Can be polished beautifully, and polishing efficiency has improved.
